SPECIFICATION forming part of Letters Patent No. 794,121, dated July 4,1905.

Application filed June 1, 1903. Serial No. 159,524.

T0 @ZZ whom it may concern:

Be it known that I, THOMAS ROBERTS, a subject of His Majesty the King ofGreat Britain and Ireland, residing at Nelson, in the Colony of NewZealand, have invented new and useful Improvementsin and Relating toWindows, of which the following is a specification.

The object of this invention is more particularly the eiiicientventilation of rooms and the like, and this is eifected by theemployment of window sashes and frames so constructed and arranged incombination that inlet and outlet currents of air can be obtainedwithout creating undesirable drafts.

By the use of my invention the outside of a window can be convenientlycleaned from the inside of a room, and, if desired, the bottom sash canbe entirely removed for this or other purposes.

In practice I construct a window with sashes arranged one above theother in the saine plane in a frame, two of said sashes being pivotallysupported at or near their lower ends, whereby they may be opened byinclining their upper ends toward the interior of the room. The sides orjambs of the said frame are parallel to the faces of the side edges ofthe sashes and are of sucient width that the sashes when opened forVentilating purposes shall not project beyond the limits of the frame,so that side drafts are prevented.

The pivot-brackets are so constructed that the bottom sash may bereadily taken out when required and to be, if desired, dropped into apocket provided for its reception.

I will now describe my invention in detail by the aid of theaccompanying drawings, wherein-.

Figure 1 is a front elevation from inside a room; Fig. 2 a verticalcentral section on 2 2, Fig. 1; Fig. 3, a sectional plan on 3 3, Fig. 1;Fig. 4, a part-sectional end elevation drawn to a larger scale; Fig. 5,a front elevation of a pivot-pin and plate; Fig. 6, a sectional plan ofthe same; Figs. 7 and 8, respectively, sectional and front elevations ofa pivot-socket; and Fig. 9, a corresponding plan.

Similar numerals of reference indicate the same or corresponding partsin all the figures.

Referring first to Figs. 1 to 4, the sashes 1 and 2 are pivoted oneabove the other at their lower ends in the frame 3, whereby they may beopened, as shown in dotted lines, Fig. 2.

The pivoting arrangement (shown in Figs. 4, 5, and 6) is particularlyfor use upon a sash which is designed to be withdrawn from the frame andcomprises for each pivot a pivot- `pin 4, made integral with a plate 5,by which it is secured by screws to the window-frame, and a plate 6,having a recess 7 formed to receive said pin, the plate being secured tothe side of the sash by screws 8 and having a channel 9 communicatingwith the recess 7, so that the pivotpin may pass out of the bracket whenthe sash is being taken out of the frame.

When it is not desired to remove the sash from the frame, thepivot-socket 10 (shown in detail in Figs. 7, 8, 9) is substituted forthe plate 6 in Figs. 5 and 6. In this arrangement the socket 35 isscrewed upon the front of the sash and receives a pivot-pin which issecured to the frame. The sash can, if desired, be turned upon the pivotto be reversed and to then hang nearly vertical.

To insure a weatherproof joint when the sash is closed, the lower edgeof the lower sash has a plowed recess 11 (shown clearly in Fig. 4)extending from side to side, which receives a tongue 12, Xed in aVgroove in the window-sill 13, and the lower edge of the sash slopesdownwardly and outwardly from said tongue. As shown in Fig. 3, the innerfaces of the jambs of the frame3 are comparatively wide and parallelwith the faces of the side edges of the sashes 1 and 2.

Both the upper and lower sashes when closed shut against stops or anges14, (shown clearly in Fig. 3,) fixed in plowed grooves in the jambs ofthe window-frame and each having a tongue 15 xed in a groove 16 andadapted to engage when the sash is closed with a corresponding groove17, formed for its reception in the outside face of the sash. Locks 18,having bolts 19, which are operable by a thumb-piece 20, are fixed uponeach side of the bottom sash, and plates 21, having recesses 22 toreceive said bolts, are provided in the window-frame, whereby the sashmay be secured when shut and when open to a convenient extent. The

IOO

top sashes may be opened and closed by means of cords and pulleys orotherwise, as most convenient. Stops 23 fit tightly into holes in theframe upon each side of and limit the opening of the sash.

The inside of the top part or soft of the frame is sloped up at anangle, as shown at 24, Fig. 2, to permit a large and free passage forair without the sash having to be opened inconveniently far, a rail 25beingprovided at the lower edge of such sloped soffit for the upper railof the top sash to close against.

A perforated frieze 26 is secured to the frame above the upper sash forornamental purposes.

A pocket 27 may be provided below the window-sill to receive the bottomsash, which may be taken out of the frame, said pocket having a cover28, which slides in grooves in each side of the frame. To prevent shockwhen the sash is passed into the pocket, buffers 29 are employed, asshown in Fig. 2, each buffer having a stern 30 sliding in or through ahole declare that what I claim is- 1. For the purpose indicated incombination sashes pivotally supported one above the other 1n aWindow-frame, said sashes having grooves in the outer faces of theirsides, jambs of the frame each having a plain face in one plane parallelwith the edges of the sides of the sashes, stops fixed in grooves formedin said jambs, and a tongue upon each stop, adapted to fit into itscorresponding groove in the outer face of sash substantially asspecified and illustrated.

2. For the purpose indicated the combination of a sash pivoted near itslower end in a window-frame, and the upper part of said frame or soffltcut away at an angle to provide a large passage for air when said sashis opened and a rail fixed in a recess formed in said soffit againstwhich the upper part of said sash butts when closed substantially asspecified.

3. In combination with a window-sash pivoted near its lower end in awindow-frame, of a soiiit or upper part of said frame cut away at anangle to provide a large passage for air when said sash is opened, arail fixed immediately below said soiit, against which the upper part ofthe sash shuts when closed, and a frieze fixed to said frame andextending downwardly in front of the portion which is cut awaysubstantially as and for the purpose speciied.

In testimony whereof I have signed this specification, this 24th' day ofJanuary, 1903,

in the presence of two subscribing witnesses. 65
